ALTADENA (CBSLA.com) — A 17-year-old girl has been killed after tumbling 200-feet off an Eaton Canyon cliff in the foothills of Altadena.

The deadly fall occurred about 11:27 a.m. Friday in the 2200 block of Pinecrest Drive.

Another hiker, identified as an 18-year-old man, was rushed to Huntington Hospital in Pasadena for treatment of non-life threatening injuries.

He reportedly suffered a dislocated shoulder and bumps and bruises.

A source close to the investigation told KCAL9′s Amy Johnson that the teens were on their way back down the trail after visiting the waterfalls. They were with two others at the time.

Late Friday, the deceased was identified as Esther Suen of Alhambra.

The popular spot for hikers is off the 210 Freeway and is considered very dangerous. Firefighters say they’re called to the location about once a week for a rescue or body recovery.

There were two reported deaths at Eaton last year.

Lisa Derderian of the Pasadena Fire Department warns inexperienced hikers to stay on marked trails. “Often we find people not dressed properly or not prepared. They’re in open-toed shoes. They slip and fall. It’s very loose terrain.”
